EVENTS
18:00 stop science issued for ACIS 3x3, OBSID 62724.
18:06 ACIS confirms radiation protection ATS has executed.

Change to OBSID 62486 at 18:45, for earth sensor scan. 

LOS from Diego, 20:38. Pick up Diego again at 21:16.
Lose 2 fid lights. Reacquire with CAP 129, option 3.
22:23 LOS from Diego. Pick up Goldstone 23:47

00:11 switch to format 4.

00:00 start earth scan 20

01:00 Execute CAP 129 with option 3 FID lite magnitudes. One
light is acquired in slot 0 so CAP is run again. All 4 lights
acquired in proper slots.

NOTES/ISSUES/PROBLEMS
After ACIS door opening, OAC Phase 1, Mission Planning will 
only cover the day Shift, shift B, 09:19am to 21:19. So
we need to coordinate ALL schedule updates during that shift,
for Phase 1.

Late switch to format 4 caused some loss of earth scan 20 data.

Flight note 214 was issued reporting an inferrence of spurious commands. 
During solar array range of motion test, around 217:18:37, software
found extra commands not thought to be sent. 3 received at OBC
at time only one was sent. An extra Enable SCS 8 command
was received, and flagged as an error because was already 
enabled.
